Mods and experiences with our Robo 3D R1+ (1st Printer)

I'm sending a print from MC. I notice although it set the target temp for the bed. It doesn't for the extruder. I'm gathering the G-code.

 

Well, it set the target temp for the extruder after the bed hit it's target temp. Wierd

 

I guess I never noticed before.

I still only see the "Error: line number is not last line number+1" again after it got up to temp it started the bed probe stopped and powered down. Starting again and made a bad studder then started printing off the bed. I was watching the G-code no errors came back while it did this.

 

Although I'm not seeing any temp errors in the G-code, I went up and down the G-code, I'm thinking its the thermistator, or a loose wire somewhere.

 

So the things I tried last night,

Tried sending a print from my SD card using the LCD screen. Same results
Sent a print from MC and watched the G-code terminal. Same results

It starts the 9 point probe and stops at different points. After going through what seems to be a power re-cycle it starts back up, but starts printing right where the head stopped. Generally about an inch off the bed. It seems like if I let it go it would continue to print, but of course I kill it.

I've been messing with the print head a lot lately maybe somethings loose there. I'll run a couple other tests tonight and watch the G-code terminal. Perhaps take out the thermistor and clean it out again as I did before. and look for any other loose wires.

I called Robo and they said I would have to schedule an appointment with a tech, but their hours are the same hours I'm at work.

 

I've been using Cura. I'm only using MC to hook up and review the G-code it's spitting out. The print I sent fropmt he SD card was sliced in Cura. So I've sent a print sliced in Cura and in MC and recieved the same results.

That is interesting thing you mention. I installed a 80mm fan beside the Ramps board blowing air out of the case shortly after I got the printer to help with cooling. I'll check that little one. I can feel the big one I installed blowing air out of the case.

 

Thanks Mark,

I'll look into these things tonight.

Wife said a big box arrived. I think that's the Flsun kit I ordered.

I also received that kit I bought that has the ramps board and drivers in it a couple of days ago.

Printer kits and parts are starting to stack up. LOL

 

Pretty inconsistent with the way it's acting. When I got home I decided to turn it on and send a print from the SD card just to see what happens. It made the first bed probe and then powered down for about a minute, came back to life but all the temps were set at 0. Tried again. This time it made it through the bed probe but stopped about two minutes into the print. Tried a third time after resetting failsafes in the LCD. Shut down after the first bed probe. Power is still coming from the power supply because that extra fan I installed that's powered directly from it is still going.

It seems like the little fan on the ramps is going.

Anyway I uploaded the G-code from a failed print last night

There's a video of it shutting down. Thermistor shorting out?

 

Not associated with the issues you are experiencing but did anyone else notice in the video it homed Z in the corner before the ABL (which yours is drastically slow by the way lol)? In my experience the Robo homes Z in the middle of the bed.

 

Is there an advantage to homing Z that way?

 

A nice guy from our FB group is sending me an after market one, but I'm not sure if it will work. He says he put it on his. so we'll see. I also put in a replacement part request with Robo.
